ISL9014IRKPZ

Voltage Regulators - Linear, Low Drop Out (LDO) Regulators Overview

The ISL9014IRKPZ is a dual-output fixed positive Low Dropout (LDO) regulator manufactured by Intersil, now part of Renesas Electronics. It operates within an input voltage range of 2.3 V to 6.5 V and provides two independent outputs with a maximum current capability of 300 mA per channel. The device utilizes a DFN-10 package measuring 3 mm x 3 mm. Key electrical specifications include a line regulation of 0.2 %/V and load regulation of 1 %. The quiescent current is typically 45 µA when both LDOs are active, dropping below 0.1 µA in shutdown mode.

Voltage Regulators - Linear, Low Drop Out (LDO) Regulators Feature Summary

Voltage Regulators - Linear, Low Drop Out (LDO) Regulators Procurement Notes

Verify component authenticity through authorized distributors or direct manufacturer channels due to potential availability constraints. Confirm RoHS compliance status and specific manufacturing date codes against project requirements. Ensure proper handling procedures are followed as the device is sensitive to electrostatic discharge. Review official datasheets for any recent design changes or obsolescence notices before finalizing procurement plans.

Voltage Regulators - Linear, Low Drop Out (LDO) Regulators Selection Notes

Select this component when dual isolated LDO outputs are required from a single supply rail. Consider the 300 mA output current limit per channel against system load demands. Evaluate the need for external noise filtering via the reference bypass pin based on application sensitivity. Verify that the input voltage range accommodates the source supply variations under all operating conditions.

Voltage Regulators - Linear, Low Drop Out (LDO) Regulators Part Context

The ISL9014 belongs to the ISL9014 series of dual LDO regulators designed for low-power applications. It shares architectural similarities with other Intersil/Renesas LDOs but is distinct in its dual-output configuration and specific noise performance characteristics. The series targets portable electronics where space and power efficiency are critical constraints.

Voltage Regulators - Linear, Low Drop Out (LDO) Regulators Replacement Considerations

Consult official Renesas documentation for qualified replacement parts. Cross-reference specifications such as output current, package type, and electrical parameters to ensure compatibility.
